Description

Technical Field

[0001] This application relates to the field of asphalt repair technology, and in particular to an asphalt crack sealing device. Background Technology

[0002] Asphalt is a dark brown, complex mixture composed of hydrocarbons of varying molecular weights and their non-metallic derivatives. It is a high-viscosity organic liquid, mostly existing in liquid or semi-solid petroleum form, with a black surface, and is soluble in carbon disulfide and carbon tetrachloride. Asphalt is a waterproof, moisture-proof, and corrosion-resistant organic cementing material. Asphalt can be mainly divided into three types: coal tar pitch, petroleum asphalt, and natural asphalt. Coal tar pitch is a byproduct of coking. Petroleum asphalt is the residue after crude oil distillation. Natural asphalt is stored underground, sometimes forming mineral layers or accumulating on the earth's surface. Asphalt is mainly used in the coatings, plastics, and rubber industries, as well as in road paving.

[0003] The existing patent, CN218175538U, describes an asphalt crack sealing device for highway maintenance. This patent uses infrared sensing to detect the human body near the crack sealing nozzle and to detect the temperature of the asphalt being sealed based on the detection results. The infrared detection results and temperature detection results are used to control the alarm to sound. During the crack sealing process, the device detects and warns of the human body approaching the crack sealing nozzle, alerting nearby personnel and operators, thus improving the safety of the crack sealing equipment.

[0004] In their daily work, the inventors discovered that the aforementioned asphalt crack sealing device for highway maintenance is mainly for repairing large cracks. However, most cracks in asphalt highways are caused by small cracks that are not repaired in time, which leads to the cracks getting bigger and bigger. When repairing small cracks, it is not necessary to carry a large amount of asphalt. However, the aforementioned patent is more inconvenient when repairing small cracks due to its larger size.

[0025] To address the aforementioned issues, this application provides an asphalt crack sealing device that facilitates the repair of small cracks.

[0026] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0027] See Figure 1-2 The asphalt crack sealing device includes a storage cylinder 1, a handle 4 fixedly installed on the outer wall surface of the storage cylinder 1, a discharge pipe 5 fixedly installed at the bottom of the storage cylinder 1, and an extrusion device 2 provided at the top of the storage cylinder 1 to facilitate the extrusion of asphalt into the storage cylinder 1 for repairing cracks.

[0028] The extrusion device 2 includes a cover 21 covering the top surface of the storage cylinder 1. A feed pipe 22 is fixedly installed through the surface of the cover 21. A telescopic hose 23 is fixedly installed at the lower end of the feed pipe 22. An extrusion plate 24 is fixedly installed on the outer wall surface of the telescopic hose 23. Two electric telescopic rods 25 are fixedly installed on the surface of the cover 21. The output end of the electric telescopic rods 25 is fixedly connected to the extrusion plate 24. A solenoid valve 28 is installed on the discharge pipe 5. The storage cylinder 1 is made of double-layer stainless steel with an inner Teflon anti-stick coating. The discharge pipe 5 is threadedly connected to the storage cylinder 1.

[0029] During operation, the storage cylinder 1 is made of double-layer stainless steel with an inner Teflon anti-stick coating and has a volume of 5L. The discharge pipe 5 has an inner diameter of 3-6mm and can be replaced with a standard 5mm pipe. It can be quickly switched via threaded connection to adapt to different crack widths. The electric telescopic rod 25 has a stroke of 100mm and a thrust of 500N. The telescopic hose 23 is a Saint-Gobain Norprene® 1050 silicone hose, and the solenoid valve 28 is an Airtac SOL-20. By setting the extrusion device 2, the extrusion plate 24 can be moved out from inside the storage cylinder 1, thereby extruding the asphalt inside the storage cylinder 1 from the discharge pipe 5 to repair the crack. This makes the device easy to repair small cracks. The asphalt crack filling device can be easily moved and operated by holding the handle 4.

[0030] The cylinder cover 21 is installed on the top of the storage cylinder 1. Asphalt is fed through the feed pipe 22 and then enters the storage cylinder 1 through the telescopic hose 23. When not in use, the solenoid valve 28 is closed. When in use, the solenoid valve 28 is opened, and the extrusion plate 24 is pushed by the electric telescopic rod 25 to squeeze the asphalt inside the storage cylinder 1 out of the discharge pipe 5 to repair the cracks.

[0031] In some embodiments, the extrusion device 2 further includes a battery box 26 fixedly installed on the surface of the cylinder cover 21. The battery box 26 contains a battery, and a PLC controller 27 is fixedly installed on the top surface of the battery box 26. The PLC controller 27 and the electric telescopic rod 25 are electrically connected to the battery inside the battery box 26. The solenoid valve 28 is electrically connected to the battery inside the battery box 26 and the PLC controller 27.

[0032] During operation, the battery box 26 contains a Bosch S500 12V lithium battery, which can support continuous operation for 2 hours to meet the needs of outdoor power-free scenarios. The PLC controller 27 is a SIMATIC S7-1200, and the electric telescopic rod 25 is a JQD-06 DC electric actuator.

[0033] See Figure 3-4 In some embodiments, the two annular sidewalls of the cylinder cover 21 are provided with fixing devices 3 for fixing the cylinder cover 21 and the storage cylinder 1. The fixing device 3 includes an L-shaped plate 31 fixedly installed on the two annular sidewalls of the cylinder cover 21. An extension plate 32 is fixedly connected to the inside of the vertical end of the L-shaped plate 31. A threaded hole 33 is opened on the surface of the extension plate 32. An L-shaped bracket 34 is fixedly installed on the outer wall surface of both sides of the storage cylinder 1. A bolt 35 is threadedly connected to the surface of the vertical end of the L-shaped bracket 34. The bolt 35 is threadedly connected to the threaded hole 33.

[0034] During operation, bolt 35 and threaded hole 33 are threaded together to fix cylinder cover 21 and storage cylinder 1 together. When the device is needed, liquid asphalt heated to 160°C is first fed into the storage cylinder 1 through feed pipe 22. When the storage cylinder 1 has stored a sufficient amount of asphalt, the feeding is stopped. The materials used in the device can withstand liquid asphalt at 160°C. Then, by holding handle 4, the discharge pipe 5 is aligned with the inside of the crack. Then, the PLC controller 27 controls the opening of solenoid valve 28 and the activation of electric telescopic rod 25. The opening of solenoid valve 28 puts the discharge pipe 5 in the open state, while the activation of electric telescopic rod 25 drives the extrusion plate 24 to move. The movement of extrusion plate 24 pulls the telescopic rod. The hose 23 extends, and then the extrusion plate 24 moves to squeeze the asphalt inside the storage cylinder 1 into the crack through the discharge pipe 5, completing the repair work. After the repair is completed, the PLC controller 27 controls the solenoid valve 28 to close and the electric telescopic rod 25 to retract. The bolt 35 can be turned to unscrew the bolt 35 from the threaded hole 33. The separation of the bolt 35 and the threaded hole 33 causes the extension plate 32 to lose its limit inside the L-shaped plate 31. The loss of the limit between the cylinder cover 21 and the storage cylinder 1 causes the cylinder cover 21 to lose its limit. At this time, the cylinder cover 21 can be removed from the surface of the storage cylinder 1, and then the inside of the storage cylinder 1 can be cleaned, further improving the practicality of the device.
